Abstract
Bacillus thuringiensis and Bacillus larvae were tested as biocontrol agents against Ceratitis capitata larvae, Results showed that when larvae of C . capitata fed after five days from egg hatching at any of the tested concentrations (1.25,2.5,5,10) CFU/ml, the highest percentage of mortality occurred with the first three days following application, then the larval mortality started to decrease. The LC₅₀ of the most potent isolates (B. thuringiensis) was 3.5, this was followed by B. larvae 8.)
